Well, it’s December 22 and if you don’t already have a Christmas tree, you may be panicking a little bit because you don’t have much time left. Fortunately, Hennessey Performance is at the leading edge of science testing which car will get you home the fastest with a Christmas tree on its roof.

The high-performance tuner has been running these tests since 2019 when it sent a Jeep Grand Cherokee Trackhawk SRT that it had tuned to make 1,000 hp (1,014 PS/756 kW) down a runway and it managed to hit 181 mph (291 km/h).

Not bad, but if you’re really in a hurry, every mile per hour counts. So the team kept testing. In 2020, Hennessey sent a tuned Ford Mustang Shelby GT500 down the track for another video. It didn’t post the top speed, though, so we can assume it didn’t break the Jeep’s record.

This year, they decided that the record had to be beaten, so John Hennessey sent his personal 750 hp (760 PS/559 kW) tuned Porsche 911 Turbo S down the runway and they must have thought it would earn itself a record because the car was clocked at 206 mph (332 km/h) without a tree.

Whether it’s simply the drag or a combination of the drag and the effect that the disturbance had on the Porsche’s ability to breathe is hard to know, but with a Christmas tree on its roof, the car only managed to go 175 mph, falling short of the record.

But surely there’s something out there that can dethrone the SUV. And as many of us have done recently, Hennessey turned to a German wagon. Tuned to make 800 hp (811 PS/596 kW) and belonging to John’s wife, Hope, the team was sure they would beat the record this time with their Audi RS6 Avant.

Similarly to the Porsche, the Audi was much slower with a tree on its roof than without, but at the end of the runway, it managed to reach a top speed of 183 mph (295 km/h), officially making it the vehicle of choice for those with big budgets and limited time to purchase a Christmas tree.

And never you mind that a six-foot-tall (1.8-meter) Douglas fir could probably just fit inside the wagon. Science isn’t about being sensible, it’s about doing inadvisable tests to find the answers to silly questions.

“This was a fun way to end our most recent high-speed testing session with our Venom F5. After all, who needs reindeer when your wife has an 800 bhp sleigh?” asks John Hennessey.
